Scale The Item

Hello, i’m trying to get the item scaling to work for my PHP script.

Let’s say we have Emberscatter Treads which is base 890 ItemLevel (taken from dbc, i know it is 900 on live), we also have set of bonuses:

3563,1572,3337, these bonuses indicate that item is Mythic Titanforged by +100 ilvl, no problem with scaling item level, but im wondering where are all these “scaling mechanics” for stats located in the db2.

Any help is really appreciated!
